Cloud Computing: Main Objectives

15.06.2010 4

Understanding business opportunities

• Faster time-to-market, and cost-effective innovation processes

• Dynamic (trans-)formation of open service and business networks

• Leveraging the participation Web and mass programming

Internet-scale service computing

• Provide and consume sophisticated infrastructure, platforms and business applications as modular (Web) services

• Disrupt traditional industries and offer rich, highly dynamic experiences

Enterprise-grade systems management

• Under-utilized server resources waste computing power and energy

• Over-utilized servers cause interruption or degradation of service levels

Business Cases & Perspectives

Cloud Ecosystem


LaaS offers fast and easy provisioning of multiple interelated Cloud components

Goal: Cloud Computing system that allows coordinated provisioning of multiple, disjoint and complete system landscapes

Therefore images containing the different components/systems of the landscape are parameterized and instantiated

Also relations and constraints between the components of a landscape are considered during image construction and instantiation and inside the landscape/cloud controller

The landscape provision service must allow for altering of the system landscape setup to satisfy changing customer needs

Typical use cases related to the altering of a system landscape include

• Adding additional systems to overcome high loads or extend the functionality

• Replace systems inside the landscape

• Remove systems from the landscape

In this Use Case comprehensive SAP system landscapes shall be provided

• basically for test and development

• on demand to a customer as a self-service in a LaaS fashion

• under consideration of relations and constraints inside the system landscape

Constraints given by a SAP system landscape

• can be implemented by configuring images accordingly as well as by enforcing constraints inside the controller of the landscape provisioning system

• During image definition specific constraints like f.i. transports between SAP systems (DTP/DQP-landscape) can be predefined

• In a landscape/cloud controller the instanciation sequence of SAP systems can be policed f.i.

Research Agenda for the European Cloud Community

15.06.2010

Main Recommendations:

• R1: EC should stimulate research and technological development

• R2: EC together with Member States should set up the right regulatory framework to facilitate the uptake of Cloud computing

Additional Recommendations:

• AR1: The EU needs large scale research and experimentation test beds

• AR2: The EC together with industrial and public stakeholders should develop joint programmes encourage expert collaboration groups

• AR3: The EC should encourage the development and production of (a) Cloud interoperation standards (b) an open source reference implementation

• AR4: The EC should promote the European leadership position in software through commercially relevant open source approaches
